  1. Relative abundances of individual components to the specimen’s total peak area are given for different Eciton burchellii foreli castes, different parasite species, and Eciton hamatum intermediate workers. Values represent means of each category (for sample sizes for each category see Results). Abbreviations: RI retention index, tr traces detected, − not detected
